/// @def PW_SPAN_ENABLE_ASSERTS
///
/// @brief Controls whether `pw_span` includes asserts for detecting disallowed
/// span operations at runtime.
///
/// For C++20 and later, this replaces `std::span` with the custom
/// implementation in `pw_span` to ensure bounds-checking asserts have been
/// enabled.
///
/// This defaults to disabled because of the significant increase in code size
/// caused by enabling this feature. It's strongly recommended to enable this
/// in debug and testing builds.
